Barbwire XL had troubles

[RKM 3D Designs]

so I wanted to get a metal prop so I ordered an X432 balanced and sharpened.
well I was a dummy and didn't check what the shaft size the prop mounts to.
and I received the prop (so nice by the way) it had the 1/8" hole for the shaft.

I go to put it on the barbwire XL the shaft seems more like 5/32.
so my question now is what prop do I get for the barbwire XL.

I do not plan on upgrading the motor or ESC

I run stock with a max amps 2800 3s 100C pack.(I think its 100c, I don't think I got the 150c)

any help on the right prop choice would be great.

Thank you,
RKM

Dont know the boat personally but given what size the shaft is i would venture a guess that it is running a 4mm shaft on it, considering that 5/32" is 3.968 mm...

so the boat normally uses a 30mm prop from what I understand.
so that would mean I probably should get a 3/16" shaft size prop, problem is I have no idea what the pitch should be for this boats stock esc and motor.
and should it be 3 blade or 2? I forget it the 3 blades make things heat up too much.

what is the best prop size diameter for this boat. I cant find anything for the stock setup to clue me in here, so I don't burn something up motor, esc and such.
